What is the rate law for the overall reaction represented by the diagram below where the black circles are carbon and red circles are oxygen if the 2nd step is the rate-determining step?

Diagram showing reaction mechanisms with carbon and oxygen molecules for chemical kinetics.

문제 32객관식

Consider the reaction below:

A + C → AC

The reaction is first-order in A and first-order in C.

Two mechanisms are proposed for the reaction:

Mechanism 1 (single-step):

A + C → AC

Mechanism 2:

B + C ↔ BC fast

A + BC → AC + B slow

Are both mechanisms valid? If yes, what experimental data would you need to identify to favor mechanism 2?
